Specification of Letters'Patent.

Application filed August 17, 1914. Serial-No. 857,157.

plurality of brooms together by threadinga cord or tape through the brooms.

The invention consists of still other novel features of construction and combinations of parts which will be hereinafter described and pointed out in the claims.

In the accompanying drawings: Figure 1 is a view in side elevation; Fig.

2 is a top plan view with the covers and shields removed showing the internal moving parts; Fig. 3 is a perspective view of the sliding head with a portion of the head broken away to show the man ner of actuating the head; Fig. 4: is a perspective View of one of the eccentric roller pins; Fig. 5 is a view in elevation and partly in section of the needle-adjusting screw; Fig. 6 is a view in elevation of the needle rollers showing the needle in section supported by the roller; Fig. 7 is a detail view of a spring for holding the head in its forward position; and Fig.8 is a detail sectional view showing the slot through which the needles pass in'thebody.

A represents the body or frame of the machine supported upon a pedestal 1. Slidably mounted upon the frame and within the sides thereof is a head 2.

The head 2 is provided with a rack bar 3, which extends longitudinally thereof, and which meshes with a pinion 4 mounted on the shaft 5, which shaft is journaled in the body A. A crank handle 6 is connected to the shaft for rotating the same. Connected to the head are needles 7, 7. These needles are fastened to the head by means of screws 8, 8,which pass therethrough and through the sides of the head, and are capable of being adjusted for moving the needles transversely of the body. The needles pass through elongated slots 9 in the forward end of the body A, and in some instances, it is necessary to bring the needles closer together than in other instances, this depending en- Patented Apr. 11, 1916..

the body A, through which a screw drivercan be inserted for engaging the screws 8 when the head is moved to the forward end of the machine for the pur ose of adjusting the position of the needles Pins 11 are mounted in the sides of the body adjacent.to the end thereof, and are held in position by thumb screws 12.v These pins are provided with studs 13, which are eccentrically mounted thereon. Some antifriction means, such for instance, as a grooved roller 14 is mounted on each side of the studs, and is held thereon by means of cotter pins 15. These antifriction means or rollers 14 are located in the rear of the slots 9, so as toreceive or separate'the needles 7. The pins 11 are intended to be adjusted the same, for instance, as the screws 8, when it is necessary to move the needles 7 transversely of the machine.

The screws 8 are held intheir adjusted positions by means of thumb screws 16, so that it is necessary to release the screws 12. and 16 from the rollers or pins. 11 and the screws 8 before any adustment can be made of the needles 7.

A spring 17 is connected, to the base of the body A,,and is provided with a stop 18 thereon, which is adapted to engage the rear end of the head 2 for holding the head at the forward end of the machine duringthe placing of the brooms upon the needles. 7 The link 19 is connected to the spring and is connected to a lever 20 which is fulcrumed practically midway of its length to the post 1, so that upon the actuation of either end of the lever 20, the spring 17 will be drawn downward for releasing the head 2, so that the head can travel rearwardly upon the rotation of the shaft 5. Stops 21 are formed at the forward edge of the head, and on the under side thereof for engaging the bosses 22 on the body A for limiting the rearward movement of the head. An extension or shield 23 is connected to the rear end of the body A, and is adapted to cover the top of the machine for limiting the movement of, and covering, the head 2, as it is moved rearwardly to its limit of movement. The upper part of the body is covered by means of covers or lids 24 and 25, so that nothing will fall into the machine, and interfere with the operationof the head. In the operation of the machine, the head 2 is moved forward to the position as shown in Fig. 2, and the brooms are placed thereon. The operator will first force a broom onto both needles,

movement of the head 2 causes the forward end of the machine to act as a stripper for forcing the brooms from the needle. As the needles are drawn through the brooms, the thread or cord will be drawn through the brooms, and upon the removal of the needles, the ends of the strings will be tied to gether for tying the several brooms together.

VWth a machine of this character, wherein horizontal needles are provided, the brooms,

after they have been removed from the needles, or the needles have been withdrawn from the brooms, and the thread or cord has been drawn through the brooms, will have a tendency to lean against the end of the machine until the operator of the machine can tie the ends of the cord together for fastening the brooms together.

Another objectof this invention isin the provision of closed eye needles, so that there is no danger of the eyes catching and damaging the twine with which the broom is sewed. Furthermore, by using movable needles, the operator is always close to the brooms, as they are released from the needles, and if necessary can catch them if there should be any danger of the brooms falling to the floor and becoming disen- Copies of this patentmay be obtained for gage d. It is also very to force the brooms onto a large needle, and large needles Will elther displace ,or break the twine 1. In a broom bunching machine, the combination with a frame, a movable head, needles connected to the head, and means adjustably supported on the frame for governing the elevation of the needles.

2. In a broom bunching machine, the combination with a frame, a head and means for moving the head back and forth, of needles carried by the head and extending through the end of the frame, means for adjusting the needles laterally, and adjustable antifriction means carried by the frame for supporting the needles as they are moved in and out.

3. In a broom bunching machine, the combination with a frame having elongated horizontally disposed slots in the forward end, of a head fitted to the frame, means for moving the head in and out, needles secured to the head extending through the slots, separate and independent means for adjusting the needles, both horizontally and vertically, one means connected with the frame and the other with the head.

In testimony whereof we affix our signatures in the presence of two witnesses.
